Senior Software Engineer | Team Leader2014 - 2015iTopTraining
Technologies: Ruby on Rails, Angular, D3.js, Spark, Python, Elasticsearch
- Developed a visual tool for semantical analysis and the correlation of educational content in order to assist and speed up the process of learning.
- Created an Angular application and advanced D3.js modules to reinvent the student navigation of the content in an intuitive and graphical way.
- Built a Rails API based application to coordinate all the different technologies involved in the platform.
- Designed and implemented the big data architecture and processes to properly capture, manipulate, and store huge amounts of data from the students; used an AWS EC2 auto-scalable cluster.
- Devised and executed the machine learning algorithms to properly interpret and correlate the previously acquired data to generate a recommended learning process; used PySpark, Scikit-learn, and MLLib.
- Developed real-time communication modules in Node.js.
- Worked with different case-specific databases. Neo4J (graph data), Redis (cached data), MongoDB (general purpose data), Cassandra (fast-access data), and Elasticsearch (semantical data).
Software Engineer2013 - 2014Concurrent Thinking
Technologies: Ruby on Rails, Angular, Crystal, WebGL, HTML5, SCSS, TDD, BDD, Python
- Collaborated in the development of a complete data-center management solution.
- Migrated the legacy code from Rails 2 to Rails 4, applying TDD (RSpec) and BDD (Cucumber) in the process.
- Encapsulated of all the back models and processes in an independent Rails API based application.
- Developed a completely new AngularJS application to connect with the previously isolated API and divide the previously monolithic application.
- Implemented WebGL-based modules into the Angular application to generate a tridimensional user interface to manage the data center.
